The CAS Registry Mumber 1256729-22-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,7,2 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256729-22:
(9*1)+(8*2)+(7*5)+(6*6)+(5*7)+(4*2)+(3*9)+(2*2)+(1*2)=172
172 % 10 = 2
So 1256729-22-2 is a valid CAS Registry Number.
